2024-01-29ip: don't export useless error counters for ip6 rewriteArthur de Kerhor1-0/+4
the error node is set to ip6_input in the inline funcition associated with ip6_rewrite. Thus, error counters defined for node ip6 rewrite are never used. Type: fix Change-Id: Id6bef633928b0fff9069498c2e39e9f5bea2cf9b Signed-off-by: Arthur de Kerhor <arthurdekerhor@gmail.com>
2023-11-03tests: refactor asf framework codeDave Wallace1-4/+2
- Make framework.py classes a subset of asfframework.py classes - Remove all packet related code from asfframework.py - Add test class and test case set up debug output to log - Repatriate packet tests from asf to test directory - Remove non-packet related code from framework.py and inherit them from asfframework.py classes - Clean up unused import variables - Re-enable BFD tests on Ubuntu 22.04 and fix intermittent test failures in echo_looped_back testcases (where # control packets verified but not guaranteed to be received during test) - Re-enable Wireguard tests on Ubuntu 22.04 and fix intermittent test failures in handshake ratelimiting testcases and event testcase - Run Wiregard testcase suites solo - Improve debug output in log.txt - Increase VCL/LDP post sleep timeout to allow iperf server to finish cleanly. - Fix pcap history files to be sorted by suite and testcase and ensure order/timestamp is correct based on creation in the testcase. - Decode pcap files for each suite and testcase for all errors or if configured via comandline option / env var - Improve vpp corefile detection to allow complete corefile generation - Disable vm vpp interfaces testcases on debian11 - Clean up failed unittest dir when retrying failed testcases and unify testname directory and failed linknames into framwork functions Type: test Change-Id: I0764f79ea5bb639d278bf635ed2408d4d5220e1e Signed-off-by: Dave Wallace <dwallacelf@gmail.com>
2022-05-10tests: replace pycodestyle with blackKlement Sekera1-35/+38
Drop pycodestyle for code style checking in favor of black. Black is much faster, stable PEP8 compliant code style checker offering also automatic formatting. It aims to be very stable and produce smallest diffs. It's used by many small and big projects. Running checkstyle with black takes a few seconds with a terse output. Thus, test-checkstyle-diff is no longer necessary. Expand scope of checkstyle to all python files in the repo, replacing test-checkstyle with checkstyle-python. Also, fixstyle-python is now available for automatic style formatting. Note: python virtualenv has been consolidated in test/Makefile, test/requirements*.txt which will eventually be moved to a central location. This is required to simply the automated generation of docker executor images in the CI.

2022-03-04ip: rate-limit the sending of ICMP error messagesNeale Ranns1-2/+2
Type: improvement For error conditions, such as TTL expired, dest unreach, etc, Rate limit the sending of ICMP error messages. The rate limiting is done based on src,dst IP address of the received packet. the rate limit has been chosen, somewhat arbitrarily, to be 1e-3. This is the same limit as the ARP throttling.

2019-11-05misc: Fix python scripts shebang lineRenato Botelho do Couto1-1/+1
Type: fix Since CentOS 8, RPM build script doesn't accept '#!/usr/bin/env python' as a valid shebang line. It requires scripts to explicitly chose between python2 or python3.

2019-11-05ip: Fragmentation fixesNeale Ranns1-2/+1
Type: fix if the packet is about to be fragmented, then don't call any of the actions that expect the rewrite to have been written. 1) don't double count packets thru the adjacency (original & fragments) 2) don't double decrement the TTL for fragments 3) return to ip4-midchain post ip-frag if that's where we started. 4) only run midchain/mcast fixups if not fragmenting (if no errors) Change-Id: Ib2866787a42713ee5871b87b597d8f74b901044b Signed-off-by: Neale Ranns <nranns@cisco.com>
2019-06-18fib: fib api updatesNeale Ranns1-1/+1
Enhance the route add/del APIs to take a set of paths rather than just one. Most unicast routing protocols calcualte all the available paths in one run of the algorithm so updating all the paths at once is beneficial for the client. two knobs control the behaviour: is_multipath - if set the the set of paths passed will be added to those that already exist, otherwise the set will replace them. is_add - add or remove the set is_add=0, is_multipath=1 and an empty set, results in deleting the route. It is also considerably faster to add multiple paths at once, than one at a time: vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.11 100000 routes in .572240 secs, 174751.80 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.12 100000 routes in .528383 secs, 189256.54 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.13 100000 routes in .757131 secs, 132077.52 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.14 100000 routes in .878317 secs, 113854.12 routes/sec vat# ip_route_add_del 1.1.1.1/32 count 100000 multipath via 10.10.10.11 via 10.10.10.12 via 10.10.10.13 via 10.10.10.14 100000 routes in .900212 secs, 111084.93 routes/sec Change-Id: I416b93f7684745099c1adb0b33edac58c9339c1a Signed-off-by: Neale Ranns <neale.ranns@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Paul Vinciguerra <pvinci@vinciconsulting.com>

This patch separates setting of hardware interfaec and software interface MTU. Software MTU is L2 payload MTU (i.e. not including L2 header). Per-protocol MTU for IPv4, IPv6 and MPLS can also be set.
